Distillation of the two-mode squeezed state

Abstract

We experimentally demonstrate entanglement distillation of the two mode squeezed state. Applying the annihilation operator to both modes, we increase the fraction of the two-photon component in the state, resulting in the increase of both squeezing and entanglement by about 50%.
